@exxos and I have been working with
@Smonson to help with the HDMI development on the STFM. We have been doing a lot of work behind the scenes but the lockdown has put a delay on some of the progress so we thought we would share where we are now to give you all a sneak preview.
We have come up with a small board (and will most likely shrink further) for the H4 that will provide HDMI out through the monitor port of the case. This is one of the holy grails for an ST setup. The H4 board which is a modern remake of the STFM with lots of fixes and a plug in module to provide HDMI out with rock solid video to use on modern TV's and monitors. Although this is designed specifically for the H4 it will still work in original ST's but the HDMI would need an extension cable and an outlet out of the case.
So we started with
@Smonson's work and mashed it with our FPGA Blitter board and looking to provide the HDMI port out where the monitor port is.
@Smonson as you may of seen in this thread has been working on patching TOS for resolution switching. This great work has been a major breakthrough and shows an ST doesn't need to swap cables to change resolutions. In the previous post you can see a video of using
@Smonson board to test being able to switch into all three resolutions Low, Medium and High with the HDMi board. This is the ultimate out for video on the STFM.

And this is the first board we had made that fits the space. Spot the SEC booster as well in the H4:

We have several boards at the assembly firm but unfortunately they are still there during the lockdown:

Our next phase is to test the boards out and once working reduce the design and include audio out through the HDMi as well. The full size Max10 is pretty large so we will look at the smaller form factors to reduce the size of the board.
